    The power-frequency control of a multimachine power system model is investigated using combined boiler-turboalternator units interconnected with the general node equations of a transmission network. The boilers, represented by lumped energy storage elements, are combined with the turbine equations using flow- power relations associated with static operating characteristics. The alternators are rep... View full abstract»

    A new method is presented for finding B coefficients expressing loss in a power system as a function of power input. The computer program necessary to find these loss (B) coefficients is very simple, and transformations of variables are not required. The method takes advantage of the fact that partial derivatives of voltage phase angles with respect to any plant power output are independent of sys... View full abstract»

    The dynamic performance of an alternator supplying power on a dc link is put into equations, and the equation system is resolved in order to pick out the characteristic transfer functions of the dynamic behavior of the whole system. These functions have a simple literal form and are very practical for studying all problems of regulation which concern such systems of power production and transmissi... View full abstract»

    The use of digital computers to monitor kilivolt-ampere demand on distribution transformers is a relatively recent development. The development and operation of such an application are discussed. An analysis of the results and savings for the first three years of operation is presented, along with a brief summary of future plans for computer programs to aid in the design of distribution systems.

    In interconnected power system networks, for maintenance or other purposes, it is becoming increasingly necessary to observe numerous switching constraints in reorganizing the system for supply security following outages due to faults. The development of these constraints by deduction can become time consuming and tedious. This paper records the latest progress in the application of set theory to ... View full abstract»

    A twin-stator, axial-airgap, variable-speed, eddy- current motor is described. The speed of this motor can be continuously varied by mechanically shifting one stator with respect to the other. Results of tests performed on the motor are reported, and, based on electromagnetic field theory, an approximate analysis is presented. The speed-torque characteristics obtained from theory are compared with... View full abstract»

    The two-phase drag-cup induction machine is analyzed using a generalized machine model and the performance equations solved by digital computer. Methods of determining machine parameters are examined and a method for experimental determination of stator to rotor mutual inductance and rotor self-inductance is developed using a procedure based on the least mean squared error criterion.

    A 1962 paper [1] described the single-needle test, a method of electrically stressing an artificial fault in transparent insulating polymers for the purpose of evaluating the effects of additives in improving their dielectric strength and voltage life. This paper reviews developments in test procedure since that time. Oil has replaced air as an interelectrode medium. Other details of current techn... View full abstract»

    A new restrike-free, fast-acting, minimum oil circuit breaker for the range 60 to 500 kV is described. The breaker can be equipped with interrupters for either 40 000 or 60 000 amperes, providing a maximum symmetrical interrupting capacity of 50 000 MVA. Of the modular type, it is built from self-contained, identical, and interchangeable basic building elements. Arcing time is virtually independen... View full abstract»

    Trigatron breakdown characteristics were studied in atmospheric air for gaps up to 15 cm in length. Under negative impulse voltages with a positive trigger pulse applied in the grounded electrode, the minimum breakdown values corresponded closely to the negative sphere-rod gap breakdown values. While under positive impulses the trigatron broke down at approximately the same voltages as the positiv... View full abstract»

    Switching surge field tests were performed on a 292- mile 345-kV transmission system. Switching of lines and connected transformers resulted in surges in excess of twice normal voltage under certain conditions. Trapped charge decay on the shunt compensated lines was of such duration as to have a direct influence on high-speed reclosing transients. A number of field test conditions were reproduced ...

    The influence of overhead ground wires on the corona losses, RI, and telephone interference of dc lines was studied. Corona losses and RI were measured on a full-scale bipolar test line. Corona losses were measured on laboratory models of monopolar, homopolar, and bipolar lines. Telephone interference levels were calculated. Experimental and calculated results are presented.
